2013 polo vivo gt miss on idle

[NiKHiL_POWER_GT]

Good day.
I have a 2013 polo vivi gt.
1.6 cls engine
245000km on clock

The car seems to have a miss or hunt on idle. Soon as i accelerate. Car goes fine, clean revs no miss or hesitation. No loss of power, fuel consumtion about 210km for R400, no oil loss. When you sitting in the car or stand at the exhaust you can hear the idle sounds like its up and down.
The revs dont flux on the dash and its not noticeable at the engine bay that the car idle isnt steady.
Had issue with coil pack on cylinder 3 in august 2023 which i changed. Had to change plugs in jan2024 as car had a heavy miss.
Car is stock other than a branch and exhaust.

Any help.

check the injectors

Consider doing a compression check to rule that out.... Some of the 2010 to 2014 models did have an issue with valve guides which meant that valves were not sealing correctly which resulted in a misfire.

Will do both asap.

Had a leak on the thermostat. Which i sorted out yesterday. Flushed system and put in antifreeze. As i was running with water for some time. Car seems to hesitate and jerk on acceleration. Mech says probably blown head gasket. Allowing coolant to go by the spark plug. Says coolant is harder to burn out than the water therfore the car is giving the hesitation while driving nw.

Injectors are good and working

Will strip soon and do head gasket. Timing chain as well while in there.
